This is a Japanese folksong form, often concerning love or comedy.
From across the sea they came
Those strange, enormous bird-things.
Until they came in plain sight
We thought them cousins.
Floating, duck-like, on the tide
But their puffed-out wooden chests
And canvas wings spread so wide
Proved they were no birds
But from them came these creatures
Two-legged, tall and beautiful:
Never had we seen their like!
So we welcomed them
They smiled to see us waddle
Among them. Our snort-cluck-honks
Amused them. And they admired
Our plump, round bodies.
They gathered us in their arms.
Delighted, we snuggled close.
Throatily crooning our love
As they filled cook-pots.
